The American FBI has a secret cache of documents, more than 80,000 pages in all, concerning possible ties between the 9/11 hijackers and an upper-class Saudi family who lived in Florida and fled the United States two weeks before the suicide hijackings that killed nearly 3,000 people.

A federal judge in Tampa, Florida has been reviewing the documents for more than two years as a consequence of a Freedom of Information Act lawsuit brought by a trio of online reporters—Anthony Summers, Robbyn Swan and Dan Christensen. The review process has been extremely slow because of restrictive FBI rules on how many pages Judge William Zloch may access at any one time.

The existence of the document trove was revealed Friday in a front-page article in the US-based web publication the Daily Beast. The article identified the Saudi family as Abdulaziz al-Hijji and his wife Anoud, who was the daughter of Esam Ghazzawi, an adviser to a nephew of Saudi King Fahd. Ghazzawi owned the home in which they were staying in a gated community in Sarasota, Florida. The home was raided by the FBI after 9/11 but the residents had all departed in evident haste on August 30, 2001.

Visitor logs in the community, known as Prestancia, showed that the alleged ringleader of the 9/11 hijackers, Mohammad Atta, had visited al-Hijji, along with two other 9/11 hijackers, Ziad Jarrah and Marwan Al-Shehhi.
